What To Know

  • To view BenQ projector lamp life: Go to Menu > Information > Equivalent Lamp; or head to Menu > SYSTEM SETUP: Advanced > Lamp Settings > Equivalent Lamp.
  • Lamp longevity can be increased by using Economic or SmartEco modes: Menu > SYSTEM SETUP: Advanced > Lamp Settings > Lamp Mode > Economic or SmartEco.
  • Regular rest periods for the projector and proper cooling down after use, combined with positioning in a well-ventilated area, can significantly extend lamp life.

Below, we look at how to check lamp hours on the BenQ projector. We also provide tips and techniques on how to extend lamp life. 

Moreover, we go over reasons why projector lamps burn out earlier than expected and how to switch out lamps if that ever happens. 

How to Check Lamp Hours on the BenQ Projector

All projectors in general, and BenQ projectors in specific, have an internal lamp life timer that automatically measures lamp life. To check lamp hours on a BenQ projector, simply perform the following steps:

  1. Press the Menu button on your BenQ projector or remote.benq panel with menu button highlighted
  2. Go to the Information tab, and you’ll see the Equivalent Lamp (which shows the lamp hours).information menu of a benq projector
  3. Or you can head to SYSTEM SETUP: Advanced, and then choose Lamp Settings. You’ll see the Equivalent Lamp (which shows the lamp hours) there.lamp settings of a benq projector

Factors that Determine a Projector Lamp Life

The lifespan of a projector lamp is influenced by various factors, dispelling the misconception that it solely depends on the bulb itself. Here are four other factors that can have an impact on your BenQ projector’s lamp.

  1. Operation Mode: The operational settings of your projector play a crucial role in determining the lifespan of its lamp. Constantly operating your projector in normal or high power mode can greatly reduce its lamp life.
  2. Frequency of use: Not only your projector’s bulb, but other components can also overheat and spoil if your projector doesn’t get to rest.
  3. Air circulation: The projector needs enough air to cool after use. If the air is dusty, dirt will gather in the projector’s filters, blocking airflow and causing overheating, hence, damaging its own components.
  4. Temperature: Heat damages projectors and other electronics. Lamp projectors tend to run hot, and it gets worse if the projector is placed in a hot/poorly ventilated environment.

How to Extend Your BenQ Lamp Hours

1. Activate Your BenQ Lamp-Saving Modes

One of the most effective and direct ways to extend the lamp hours of your BenQ projector is by activating the Economic or SmartEco mode.

This mode can significantly prolong the lifespan of your BenQ bulb, allowing it to last anywhere from 1,500 to an impressive 5,000 hours.

By following these simple steps, you can easily activate the lamp-saving modes on your BenQ projector and enjoy extended lamp longevity.

  1. Press the Menu button on your BenQ projector or remote.
  2. Head to SYSTEM SETUP: Advanced, and then choose Lamp Settings.lamp settings is highlighted on a benq projector

2. Let Your Projector Rest Moderately & Turn It Off Properly

In addition to considering the frequency of use of your projector, it is equally important to allow it to rest adequately.

While the focus is often on the lamp, it is essential to recognize that other components of the projector can also overheat and potentially be damaged without proper rest periods.

Giving your projector sufficient downtime between extended periods of use allows the internal components to cool down and prevent excessive strain.

By allowing your projector to rest moderately, you promote the longevity of not only the lamp but also the overall health of the projector, ensuring optimal performance and reliability in the long run.

Additionally, after extended use, your projector requires time to cool down, particularly its bulb. This cooling process relies on the power supply to activate the fans.

Therefore, when you finish using your projector, it’s important to turn it off but refrain from immediately unplugging it.

By keeping it connected to the power source for a brief period, you allow the fans to continue cooling down the bulb.

This practice helps prevent premature lamp failure and ensures an extended lamp life.

3. Place Your Projector In a Ventilated Area

By placing your projector in a well-ventilated area, you create an environment that allows for efficient heat dissipation.

This helps to maintain the optimal temperature for the projector, reducing the risk of overheating and extending the life of the lamp.

A properly ventilated projector ensures consistent performance and minimizes the chances of premature lamp failure, providing you with an optimal viewing experience for a longer duration.

4. Clean It Regularly

Dust and dirt can accumulate in your projector over time. This amassment of dirt can stop heat from exiting the projector, which can cause your device to overheat after a period of use.

Regular dusting and cleaning can protect your projector from this situation.

Compressed air dusters are a great tool to have when you’re cleaning your projector. This machine’s long nozzle can fit into the small corners of your projector and blow away any blockages for better airflow.


Checking the lamp hours on your BenQ projector is crucial for warranty compliance and monitoring its performance. By following the provided steps, you can easily check the lamp hours using the basic or advanced OSD menu on your projector.

Additionally, understanding factors such as operational settings, frequency of use, air circulation, and temperature can impact the lifespan of your BenQ projector lamp.

To maximize lamp hours, consider activating the ECO mode on your projector, which significantly extends the lifespan of the bulb. It is also important to allow your projector to rest adequately and ensure it is placed in a well-ventilated area to prevent overheating.

Regular cleaning, including the use of compressed air dusters, helps maintain proper airflow and prevents blockages that can affect the projector’s performance.
